Specification of Letters Patent.

Application filed Juli 12, 1911.

Serial No. 638,082.

To aZZ whom it may concern:

Be it lmown thatI, WVALTER J. MoGoY, a citizen of the United States,residing at South Omaha, in the county of Douglas and State of Nebraska,have invented new and useful Improvements in Trucks, of which thefollowing is a specification.

The present invention relates to improvements in trucks for handlingboxes, and it has especial reference to box-trucks of the general typeshown and described inmy prior Patent No. 993,265. 1

A structural embodiment of the invention is illustrated in theaccompanying drawings, whereof i Figure l is a perspective View of theimproved truck, Fig. 2 is a side elevation thereof, said figures showingthe lever-operated slide inforward position. Fig. 3 is a plan View ofsaid slide, Fig. 4 is a perspective view of the clip connected to theslide, Fig.

Fig. 5 is a fragmental sideelevation of the truck, showing the slide inretracted position, Figs. 6 and 7 are detail views, of a pair of palletswhich are employed when the .truck is used for handling bricks.

Referring'to said drawings, 1 designates the square axle of the truck, 2the wheels which are rotatably fitted on the trunnions 3 on theaxlefends and 4the truck frame.

' Saidframe comprises a pair of inclined side beams 5 connected at theirupper or rear ends by a cross-bar 6, and adjacent their lower or frOIit,ends to the axle, a pair of rearward extensions? which are formed uponthe 2 lower ends of the side bean1s5, and, in turn,

have the handles 8 fastened thereto, and a pair of vertical supports orlegs 9. Legs 9 are fastened at their upper ends to beams 5' and theirlower ends are oined togetherby a cross-bar 10, the first-mentioned legends being attached to said beams at the same point as the frontends ofa pair of braces 11 whose rear ends terminate in eyes or collars 12;that are fastened to said handles. To the'upper ends of beams 5 ishinged a load-supporting platform 13 which, in the presentinstancefconsists of apair of spaced longitudinalsills 14 connectedtogether at intervals by cross-pieces 15, said sills being providedadjacent their upperends' with eyes 16through which the cross-bar 6passes. Thelower portions of these sills are provided withfL-shapedbrackets 17 that are connected with the adjacent cushioning de-v vices18, said devices being identical in construction with the correspondingparts or elements present in my prior application aboveldentlfied, forwhich reason they require no description beyond the fact that theyinclude upper and lower plates 19 and 20, and a series of interposedsprings 21', the lower plates axle.

Adjacent the wheels, and between the latter and the ends of the beam5,the axle carriesa pair of boxings 22 which are rigidly secured theretoby plates 23 held in place in any suitable manner. These boxes areprovided, inaddition to the openings through which the axle ends pass,with- Patented May 28,1912

20 being connected with the transverse passages 24 designed to looselyreceive the offset upper ends of a pair of upstanding arms 25 secured tothe rear ends of tongues 26. Said tongues are slidably received ingrooved guides 27 fixed upon the a I ends of the cross-piece 28fof afork 29, the

cross-piece having also afiixed to its central portiona lug 30. v Tothis lug is pivoted the lower end of a link 31,*composed of a pair ofcounterpart spaced members 32 which diverge toward their lower ends,said members having their upper ends introduced between and pivoted tothe lower ends of a pair of spaced arcuate links 33, whose upper endsare pivoted between the apices of a pair of angular brackets 34 arrangedin spaced parallel relation to eachother and connected at their rear orupper ends to the central portion of the cross-bar 10.

'Between the upper portionsof the link members 32 is fixed a dependingarm 35 to which is connected the forked lower end of the operating lever36, said lever being provided adjacent its upper end with a series ofnotches or teeth 37 designed to engage crossbar 10, and at said end witha handle 38.

The lower ends of the sills 14 are provided with L-shaped lifting plates39, but these are omitted when the truck isusedfor handling brick, inwhich instance the two pallets 40 and- 41 shown in Figs. 6 and 7 areemployed. The first of these pallets replaces the sliding fork and isprovided with a central lug 42 and with guides 43 which are identicalwit-h the corresponding elements on saidfork. The second, or auxiliary'pallet 41 is adapted to be carried by,

the platform 1 3,and is constructed of adjustably connected parts, so asto enable it' to be fitted to platforms of different w dths; theaforesaid adjustable parts consist, in

the present instance, of a plate or body 44 to whose opposite sides areattached a pair of laterally-flanged or angular members 45 which areformed with slots 46, screw bolts or other suitable fastening devices 47being passed through said slots and through registering openings in thebody 44 to retain said members in adjusted position.

The operation when handling boxes, is substantially as follows :Ihetruck is wheeled close enough to the box to enable the sharpened feet ofthe lifting plates to be inserted beneath the bottom of the box, thetruck having previously been shifted or tilted to bring the supportingplatform into vertical posit-ion. The handles are then swung slightlybackward to raise up the end of the box engaged by the lifting platesand the lever 36 then forced downward and forward, to move the slidingfork beneath the box. This movement of the lever forces the link 31 and,in consequence, the fork to move forward, as will be understood, and hasthe further effect of swinging the curved links 33 in the samedirection, said lever moving from the position shown in Fig. 5 to thatshown in Figs. 1 and 2, in which latter position one of its teeth ornotches 37 is engaged by the cross-bar 10, thus locking the leverinplace. To withdraw the fork it is only necessary to exert an upward pullupon the lever, whereupon a reverse movement of the latter and of theparts 31 and 33 will take place, such movement being preferablyterminated by the contact of the parts 33 with a suitable stop, as, forexample, a cross-pin 48 carried by the brackets 34. Practically the sameoperation takes place when the truck is used for handling brick, thepallets 40 and 41 being employed as above stated.

With reference to the passages 24, through which the offset ends of thearms 25 extend, it may be stated that these passages are sufficientlywide to permit play of said ends forward and backward bodily therein,sidewise play being, however, prevented. This play is necessary in orderto enable the fork 29, to remain flat upon the ground until the end ofthe box has been raised high enough to permit said fork to be forcedthereunder without interference on the part of the box end.
